Farmer John wants to label his N (1 <= N <= 1,000,000) cows, but
cows don't like having the digit L (0 <= L <= 9) written on them,
so he avoids that.

If the cows are labeled with the smallest set of N positive integers
that don't have the digit L, what is the largest number that Farmer
John has to write on any cow?

输入格式

Line 1: Two space-separated integers: N and L.

输出格式

Line 1: A single integer that is the largest number that Farmer John has to write on any cow.
